Question

Question below is followed by two statements, labelled (A) and (B). Decide whether the data given in the statements is sufficient for answering the question.

Given****Information	Column A	Column B
$\frac{a}{a+b}$ = $\frac {c}{c+d}$	cb ad

• A. The two quantities are equal
• B. The quantity in column B is greater
• C. The quantity in column A is greater
• D. The relationship cannot be determined from the information given.

Answer 1

Answer: (A)

The two quantities are equal

Answer 2

$\frac{a}{a+b}=\frac{c}{c+d}$
On solving, we get by cross multiplying,
\Rightarrow\;$$ac + ad = ac + bc
\Rightarrow\;$$\text{ad = bc Hence Column A = Column B}

The correct option is (A): The two quantities are equal
